rhis invention relates to improvements in y cutting, and folding are automatically performed, in required sequence on a web of paper drawn from a reel or roll mounted on the machine or positioned adja'centlyA thereto, to produce completed book sections having predetermined numbers of liiages.'A

' In the present invention the webof paper is' drawn from the reel or roll by means of e one or more co-acting pairs of inter-geared serrated drawing or Vtraction rolls, and is firstly ruled on one or both sides. After being ruled, as required, the web ofpaper is.

cut or divided longitudinally into two strips or ribbons of equal width, each strip or ribbon being, accordingly, half the width of the reel or roll. :4 n

rlhe separated ribbonsor` strips are nextcaused to vmove in opposite directions andi at right angies to their original course, and afterV passing around suitable guiding members,

approach each other and move `into contact and finally become superposed one upon the other, and said strips or ribbons,A with their correspondingly ruledlines accurately reg- V istered then travel in the same direction.

The superposed strips or ribbons are now' by and caught upon a series or row of needles or spikes projecting from the periphery of the collecting cylinder.

The piercing needles carry within the said periphery to-release the ends of the paper strips.

sections, whereby'the operations of ruling,

the ends of the* strips or ribbons a predetermined distancev around the periphery of the :collecting cyl-v inder, w iereupon the, needles are withdrawn vt or about the time the needles release the paper strips, 'a tucking blade,'carriedfby the collecting cylinder, venters between open grip# ping jaws, or 'shortly grippers, mounted on the cutting cylinder, aiidpushing laterally on the,superposed'l paper stripsimpels the sanieinto .tlievsaid gripp'ers which close over the ltucking v,blade and the portion of said strips therein. y Y i e The relative movement ofthe collecting andcutting cylinders'causes the tucking blade to slide outwardly from saidgr'ippers which` closing firmly" upon the ypaperfst'ripsfold. thesame. rlhe `said cylinders :have now" revolved approximately through` one half arevolution from the positions they' occupied when the needles pierced the paper strips. Upon fur,-A ther rotation the grippers paper strips around the periphery of the cutting cylinder and draw the yreleased ends of the said strips backwardly from vthe collecting cylinder. o

The folded portion of the paper strips or ribbons are ystillcon'nected with the reel or roll, and said strips or ribbonsl continue to pass between the collecting and cuttingcylin# ders and are maintained taut by the traction of the gripping jaws or grippers. `However, at the vcompletion of approximately a further half revolution and rather less than one revolution from the original point-'atwhich kthe needles penetrated the superposed paper strips, a. cutting blade on the cutting cylinder coacts with 'arubber pad on the collecting cylinder to sever the folded portions from the said paper strips.

' Theperipheral length of the cutting cylin-` der is made approximately fourtimes the width of the required exercise bookand acy cordingly at this stage a book section having four leaves of twice the lrequired width isy obtained. 1t, therefore, becomes necessary to,4 fold the section again to make it of stand-` ard'width. r A f f,

For this purpose, and whenk the said grip; pers have carriedthe section a sufficient distancev around'the periphery of the cutting f1 cylinder, a tucking blade thereon 'bears lat-' erally on the section at 'approximately the draw the folded y A mid-width thereof and inserts the paper leaves between similar spring closed gripping jaws or grippers on the delivery cylinder and re-foldsthe section to approximately Standard width in the manner -above described. `At or about the Vsame time the grippersl on the cutting cylinder open and release the previous or first fold of the section.

, The sectionv now held bythegrippers of the delivery cylinder Viscarried away from the cutting cylinder and said jaws are opened to release the section when the same has been positioned under propelling rolls... The section is finally removed from the delivery cylinder by strippers-and Vguided thereby to nipping or squeezing rolls which compress and fold', it more,tightlyuanddeposit it on interdescribed and so on continuously. Y

niittently propelled delivery belts, n i Immediately after thev folded section is severed bythe interactionof nthe said cutting blade and rubber pad,f the needles again pierce thesuperposed paper "stripsandl a further'section is produced in themanner ab'ov The successive sections are Athrown forwardly by beatersv on to the intermittently propelled delivery'belts and the said sections are thereby delivered in overlapped fan formation; i 'A Y y kBook sectionsconsisting of the two sheets l' offpaper severedV from the4 superposed strips oriribb'ons at` each revolution of the cutting andcollecting cylinders, andformedas above described, will,V when ruled in accordance with thestanda'rd system of ruling, bind into exercise books'having sixteen pages. 1

Anim ortant featureof the present invention resi es inthe provision of special counting and tripping mechanism whereby the needles carried by the collecting cylinder, in-

stead of receding within the periphery of the l.said cylinder during each revolution tliercohaie maintained in an operative position wherein they Aproject from the periphery of the collecting cylinder for two, three, four or more revolutions. Moreover, by means of thesaid counting and trippingmechanism, the closing of the grippers on the cutting cylin'derfis simultaneously delayed, so vthat al-V though-the tucking blade exerts lateral pressureon )the superposed paper strips and pushes thei'same intothe openJgrippers at each revolution, no fold is made, since the grippersdonot close Vand the paperstrips or ribbonsare merely diverted into and pass out of the same.

Meanwhile, the said counting andL tripping mechanism does not affect the normal opera- Vtion ofthe `cutting blade on the cutting cylin-A der, kand the rubber pad coacting therewith onrthe collecting.Y cylinder; accordingly, the sheets, or portions of the superposed paper stripsfor ribbons taken up by theneedles and woundarround the periphery ='of the collecting cylinder ate'ach revolution are cut away from mation on the vdelivery belts.

Vently I The folded sheets are then transferred by the Igrippers to thedelivery cylinder and,

after being again folded in themanner above outlined, are deposited in overla pecl fan forn this manner, by allowing the needles to remain in their operative positions during two revolutions, four paper sheetswill be wound u on Y thecollecting cylindenand said sheets W len folded and delivered, as above mentioned, will form book sectionsV having thirty-two pages. VVSimilarly,

,by permitting Ypaper e sheets' to mount upon thevcollecting cylinder for. three revolutions, corresponding book scctionshaving forty-eight pages willbe produced, and so on, sixteen extra pages being formed inthe book i sections for each additional revolution ofthefcollecting cylinder.

Another feature. of the invention resides inA the; provision of means whereby the rear or trailing ends ofeach pair of sheets afterthe same have been cut from the superposed strips or ribbons, are impelled'into a longitudinal gap in the collecting cylinder and maintained therein durlng'subsequent revolutions of the` collecting cylinder and until the needles thereon are withdrawn .and the grippers on the cutting .cylinder are closed by the action of the counting and tripping mechanism.

By this means the rear or trailing ends of the cut or severed sheets are maintained wit inthe said gap in a position wherein they cannot be clipped or re-cut during the succeeding revolutions of the collecting and cutting cylinders, and they remain in this positionluntil they are withdrawn from the co1- lecting cylinder by the grippers on the cut-- ting cylinder.k l A further feature of the invention consists 1n the mounting on the machine of independoperated cutting and folding mechamsm, adapted to manufacture two different standard sizes of exercise books. For this purpose' twosimilar sets of intergeared col-- lecting, cutting, and delivery cylinders are provided, the three cylinders of each set having approximately the same diameter, but the respective diameters of the cylinders of the two sets being unequal and suited to the sizes of the two different standard exercise books. Adjustable driving. means are provided, whereby one or theotherset of cylinlrl O ders may lue-operatively connected main sha-ft of the machine. Y

In these drawings the numeral lldesignates a bed Vplate havingV fixed thereto upright frames 2, spaced apart, in' parallel positions and secured and braced together by a required number of transverse members 3.

Fixed to one of the frames 2, and to the bed plate 1, are similar L-shaped members l,

which are'likewisefirmly secured in parallel positions by transverse bracesY or stays 5.

Mounted in suitable bearings in the frames 2 and on one of the L-shaped members 4:- is a main shaft 6, which may be provided with a hand-wheel 7, and with fast and loose pul-v leys 8 and 9 or withother suitable driving means or gear.

On the main shaft 6 1s a pinion 1() wh1ch lmeshes with an idler gearv 11, engaging Aa gear 12 fixed securely on a shaft 3 extending transversely between the upright frames 2 and rotatively mounted in bearings therein. Fixed adjacently to the gear 12, but on the inner side of the upright france2, is a pinion 14 which meshes with a gear 15 carried on an adjustable swinging arm 16 mounted concentrically with respect to the shaft' 13.

The adjustable swinging arm 16 is'provi'ded with a bolt 17"which'passesthrough an arcuate slot 18 in the upright frame 2,1and the said arm may be secured in adjusted positions, for purposes which will"pre's`ently appear, by tightening a nut 19 onthe bolt 17,

On the end of the shaftv 13 remote from the adjustable arm 16 is agear 20 which" meshes with van equal gear 21v carriedl onlaV shaft 22 positionedin parallelv alignment,

` driven bythe same gears"`20 and' 21.: The' shaft 22 is mounted. in bearings'25 carried on slides or plungers 26, which under the laction of springs 27 cause theroll 24`to resiliently bear upon the roll 23 preciselyas above described. The idler gear' 28 is enfA gaged with and driven Vby the gear l15 whenthe swinging arm 16 is xed in its upper po-l' sition as shewnin Figure 1, butisthrown out of action when the said armis clamped by the nut19 in its lower position asinFigure 3.

` Mounted on brackets 31 ixed lto the mem; bers 4 is'a reel or roll ofpaper 32 of required width, from which the web ofpaper is drawn by one or other pair ofserrated drawing rolls 23and24..

A spindle 33, whereon thereel of lpaper 32 is mounted is provided with an adjustable friction brake 34 of usual construction, 'hav-- ing a handle 35 and screwed shaft 36 by means of which the vfriction brake 3 4 and spindle 33 may be adjusted in an endwise direction, to locate the reel 32 in required position.

The paperweb on leaving the reel 3.2 passes around a guide roller 37 mounted on arms 38 of levers, the opposed arms 39V of which are connected to spring plungers 4 0.;

The friction brake 34 niayrbe adjusted `to provide a required tension in the web ofA paper, and thev resiliently'mounted guide roller 37, functionsv as a yieldable resistance to absorb any lsudden variations yof tension orY shocks in the paper'web. f-

The web passes from the guidek roller'3'7'` to and aroundfa guide` roller 4 1 thence to primary ruling means having a rubber covered impressionroller 4:2, rubbered duct roller43 rotating in a trough 44"of ruling ink,

On the. countershaft 55 is a gear, wheel 56 whichengages with a gear 57 mounted on the shaft 58 of the impression roller 42. Ar gear 59, fixed to the shaft 5.8 meshes with an idler 6D,which in turn.engages with and rotates ,ai gear61 mounted. on the spindle 48 of the duct 4 Y bolted to slotted supports 76, and said bar ro1ler43.Vv

The Web of paper upon being ruledy on one side the primary ruling means passes therefrom `to ay guide roller 62 lmounted on thek framing of secondary ruling means,

thence around guide roller 63, andtherefromto theimpression roller 42 of the said secondary rulingmeans. y

Thesecondary ruling means is adapted to rule the lother side of the web of paper and constructed similarly to the primary ruling means, and is provided.:withv an in'ipression` roller 42, duct roller 43, trough 44, ruling discs 45, wiper 46, means Qfor endw'ise adjustment of the duct roller 43 operated by handle 49, and central bearing-51, vcarried by thei adjustable arm 52`mountefd on astay 5.

` VThe .secondary ruling'means operated by an. idler gearv 64, which inter-connects the`lr gear 56 on thecountershaft 55 withthe gear 57 on the impressionlroller shaft 58. 'l

A gear '5 9 on the impressionroller shaft 58 drives, by means of an idler 60, the gear 6l on the spindle 48 of thedulct roller- 43, in

the same way as in the primary ruling means.

The web of paper, now ruled on one or both sides as required,vpasses from the impression roller 42 of the secondary'V ruling means, to slitting means accurately adjusted to sever or cut the said paper web longitudinally into two equal portionsor halves, thereby'forming two paper stripsor ribbons o1 exactly the same width.

The said slittingmeans, comprises rotary shears, one cutting member thereof consisting of aperiphery-blade positioned at or about the mid-length of. a roller 66 carried on a shaft y67, rotatively mounted in the opposite members 4. The other cutting member comprises a circular blade 68 carried on an arm 69 mounted on oneof the saidstays 5.

The circular blade 68 enters anarrow peripheral slot .70 in the roller 66andco`acting Withv the peripheral. blade divides the paper web into two portions of equall width as above mentioned. f V A norder to operate thesaid rotary shears a gear wheel 71 is mounted .on the shaft 67 and is driven by the gear wheel 57 on the sec- 5,

ondary ruling means by means of an intermeshmg idler gear 72. A f

The two equal Y'paper strips or'ribbons pass from the rotary shears tov a rollery 73, which directs'them to a pair of inclined turning bars 74'and`7 5 .positioned accurately atright angles to each other and located on opposite sides of the vcentral longitudinal slit inthe accordingly can be adjusted angula-rly with' respect-'to the line of division of the paper ribbons or strips and also to the bar 75,.

The upper bar 75 forms one side of Yan adjustable triangular frame, the other sides of which consists of a. cylindrical bar 77, and a fiat bar 78.' Y v A The bar 77 is atone end slidably mounted in one of the upright frames2, and is provided at its opposite end with a'threaded extension 79 which passes through a correspondingly screwed sleeve '80..rotatively mounted y in the rvframe 2. The sleeve 80 is fixed against end movement inthe frame 2, so that when it is rotated the bar 77 will be moved in an endwise direction. v i v The bar 78is A-Xed securelyand at right angles to the bar 77 and the former bar is prop CII vided with a longitudinal slot 81-'at or near its outer end. f y l One end of the upper turning bar 75 is adjustably bolted to the slotted end of thebar 78, whereas the opposite end of bar-7 5 is likewise adjustably secured to the bar 77 by abolt passing through a slot 82 in the latter.

By means of the bolts and slots 81 and82 the inclination of bar 75to the line of division of the paper and to the bar 74 may be adjusted, as necessary. w

The sleeve 8O is provided with a handwh'eel- 83, by means of which it maybe turned to move the bar 77,-and accordingly adjust the position of the frame consisting ofthe three bars 75, 77 and 78.

A support 76 is fixed'to the frame 2, near the end of the fiat bar-78 which is provided with a transverse lslot84 through whicha bolt passes intoa hole in the support 76.

On adjustment of the frame, coiisistingof the bars 75, 77 and 78, by the sleeve 80, the

said frame may be fixed in an adjusted-position by tightening the bolt passing through the transverse slot 84'.

One of the paperV strips or ribbons passes over and partly around the lower turningbar 7 4, ywhereas the other strip or ribbon passes under and partly around the upper turning bar 75.

The inclined bars 74 and 75 turn the kpaper strips or ribbons at right angles to their original course'and cause the same. to travel in opposite direction towards the ends of the frames 2 to guide rollers 85 mounted there- The paper strips or ribbons pass around the guide rollers 85 and return. towards the cen- 'ral plane of the machine, the strip turned aside by the lower bar 74 passing over agiiide roller 86, and becoming positioned above the strip diverted by the upper -bar 75, as shewn in Figure l.

By adjustment of the bar 75 by the hand wheel 83, the lowergstrip, Figure 1, mayl be positioned exactly over the upper strip, without any overlapping of the edgesof the said strips, and the lines ruled onthe respective.

strips may be brought into accurate registration.

The paper strips now accurately aligned and superposed one above the other approach andV pass between either pair of drawing rolls 23 and 24, which have drawn them firstly, as a single web of paper from `the reel or -contact witheach other, are fed to the previously mentioned folding and cutting'mecha-y nism,which as hereinbefore stated primarily comprises a collecting cylinder 87 a cutting cylinder 88, anda deliverycylinder 89.

"Tlie cylinders 87, 88 andv 89 shewn clearly apart from the machine in` Figures`4 and 5, are of approximately the same diameter and are' hollow inconstruction, and are freely mounted on shafts 90, which extend axially through them and are supported by andfixe'd securely in tlicsaid frames 2. i

The shafts 9o of the three eyiinders er, 88-

aiid 89 are parallel 'and lie" in thesaine horizontal plane, and the 'said cylinders are linter-v connected by equal inter-meshing'spur gears 91, thaty isv spur gears having equal numbers of teeth, sothatthe said three cylinders arej thereby constrained to rotate at equal speeds.y ln orderfthat bool; sectionsfof two differ-y ent sizesmay be manufactured, as previous-l ly mentioned, two setsofcylinders 87, 88 and 89 are provided, although forl some` purposes machines maybe made .having a' single set' offsaid cylinders only.` e n The two sets of cylinders and the associated mechanism, hereinafter described, co-acting'.l

therewith or respectively. governing the actions thereof, are similar in construction, ar-

rangement, and. operation, but the diameters of the icylinders` of the respective sets are dimensioned to adapttheirLperipheriesto the sizes of the two -different book sections. y

The machine accordingly may be provided with two sets of cylinders, 87, 88and 89, one

set being offconsiderably greater ysize than the other, as shewn in Figures l and 3.

Either set of cylinders may be OperatedgiV the larger set being drivenwhen the adjustable swinging arm 16 is clampedby the nut 19 Vin the uppergposition,shewny in, Figure l.v In this position the gear l5 ismeshed with and rotates the gear-28 and the latter, which at `alltimes engages the gear 91 ofthe collecting cylinder 87, drives tliefsame andthe cylinders 88 and 89 inter-gearedtherewith.l

Similarly, theV cylindersy 87 88"and 89, 'of the smaller set will be operated, when the arm- 16 is adjusted vto mesh the'V gearv-15withthe gear 91 of the collecting cylinderv;87 ofthe said set, as shewn in Figure 8. Y

Rods'12'7, passing through holesin the plates comprising the said lixed and lmovable' D. jaws, are screwedinto the side ot the said opening or gap, and springs 128 carried on the rods 127 are interposed `between the movable aw 123 andnuts 129 on the 'outer ends ot theV said rods. i j f y The -nnts 129 form abutments `for the springs 128, and the latter bear -uponthe movable jaw or plate123'and normally hold t-lie samein contact with the `fixed jaw 122', thereby maintaining the saidjaws in closed position. v ,l 'j

The ends of each ofthe shafts 126 project Jfrom the cylinders 88 and 89, and carry arms 130 having at their outer ends rotatable rollers 131, which impinge upon and ride over cams 132 andl 132 respectively, Figures 1 and 7, once during cach revolution of the said cylinders. The cam 132 hereinafter more'fully described, is of lined peripheral length in the case of the cylinder 89, but the cam 132 in the case of the cylinders 88 is capable of peripheral extension. v

Impact of the roller 131 upon the cam 132, detlects the arm 130 outwardly, and thereby rotates the shaft 126 to move the jaw 123 away from the jaw 122, and the said jaws are maintained in an open position during the passage of the roller 131 over the cani.

vThe points of impact and departure of the roller or runner 131 with and from the cam 132 and accordingly the time and extent of the opening vot' the A,said grippers, may be varied by peripherally adjusting the position on the shaft 126 et the arm 130.

mately halt a revolution to the position indiit or about this time the needles 100 are drawn inwardly below-the kperiphery of the, cylinder 87 to release thepaper strips, this movement of the needles 100 beingeectedby contact of the-roller with the cain 96,- as,y

previously described.

Synchronously wit needles V10() trom the paper strips, the tucking blade 113 on the cylinder 87 enters .be-g tween the gripping jaws 122 and 1230il thel cylinder 88, which at thisptime vare'inain tained .in anr openV position by the moi-'ement` of the roller 131 over the cani 132 as above described.

li the withdrawal of the n entering the open gripping jaws 122* and 123,the tucking blade 113 pushes laterally on the paper strips interposed between Athe'cylinder 87 and 88, andforces them into v the said open jaws to make the primaryV or firstfold in the said strips as shewn in Fig`n .k, nre 9. n y '5 During the vformation of this fold the gripping 'jaw V123 is closing, as at this time the roller 131 is moving'down the sloping end of the cam 132, and just as the fold is made the roller 131 moves away from the I said cam, and thereby permits the springs 128 to close the jaw 123 and the blade 113, and irmlyrgrip the fold within the said jaws, further movement of the cylinders subsequently withdrawing'the tucking blade 113 from the fold.V f j Y j A The closedgrippers or Vjaws 122 and'123, now firmly grasping the fold vin `the paper strips carry the same varound the periphery draw the Vends of the strips released by the needles 100 backwardly from the cylinder 87 i' the end of another half revolution, the grippers on the cutting cylinder 88 arrive Y. at the. position vshewn in Figure 10, the folded paper strips new comprising four conj tiguous sheets,- the two inner sheets being still'rconnecte'd with the paper strips enterino between the cylinders 87 and 88. c IIowever, at this time the rotation ef the cylinders 87 and 88, has -breught the saw tooth cutting blade 136 in contiguity with the rubber pad 107, whereupon the two paper Strips are gripped between the spring opc, erated. abutment blocks or 'chicken woods 137 and the rubber pad V1077 and are cut away from the entering'strips of vpaper by thieco-action of the blade 136 and the said pad.r

Immediately thereafter" the needles 100 again pierce the ends of the entering paper j strips.

The folded edges of the now severed sheets. comprising four 'contiguousstrips, are carried around the cylinder V88 for a further quarter of a revolution, at which time theV 5' flinders 87, 88 and 89 occupy the positionk s ewn in Figure 11. v

In this position the gripping jaws 122 and 123 of the cylinder 88 have been opened by .contact of the roller 131 with the cam 132,

thereby releasing the first or primary fold of the book section.

VShortly beforev the grippers or jaws 122 and 123 on the cylinder V88l release the .primary fold, the tuclring blade 113 Yon they W' said cylinder inserts the sheets laterally intoy thel grippers or jaws 122 and 123 on the delivery cylinder-89 the latter grippers or jaws being held open at this time, as the roller 131 E ,-i's' then positioned on the cam 132 governingl ofA the cylinder 88, and at the same timev The opening of the vgrippers on the cylin-r der` 88 synchronizes with the closing of the grippers on the cylinder 89 to make the second fold in the sheets, and at or about the instant the fold is made, the grippers on Y" the cylinder 88 release the primary or previously made fold, andthe now doubly folded sheets 'are carried around the periphery of the cylinder 89. Y Y

-In Figure 12 the positions of the cylinders 87, 88 and 89' at the termination of another quarterrevolution is shewn, wherein the primary fold has beendrawn backwardly from the cylinder 88, and the'second fold of the ybacksection is firmly held between the jaws 32 and-123 ofthe grippers on the cylinder In this position, moreover, the tucking blade 113 of the cylinder 87 is co-acting with the grippers ofY the cylinder 88 to make the primary fold of the succeeding book section the ends of which have just been released by the retraction of the needles 100.

In each revolution of the cylinders 87 and 88, two sheets approximately equal inV length to the periphery of the cylinder 87 are folded and cut away from the papel' strips ent-erin" between the said cylinders. However, boolo; sections consistingrr of such pairs of sheets, formed with double folds as above described, areonly suitable for the production of books having 16 pages.

In order that booksV having greater numof pages may be produced,fit is, necessary for the collecting cylinder 87 to take up the required number of 'sheets before the first fold' be described in detail.

.Mounted in .co-axially' aligned bearings in fcc thevirames 2 is a transverse shaft 147, termed c the camshaft, to which is secured a spur gear 148 similar to those inter-connecting the said three cylinders 87` 88 and 89. The spur gear 148 isconveniently meshed with the spur'r gear 91 of the collecting cylinder 87, so. that the cam shaft 147 rotates at the-same speed as the said three cylinders 87, 88 and 89, and re-j volves oppositely to the collecting cylinder 87.

Pivoted on a pin 149 fixed in one of the frames 2`is a lever 15'0, hereinafterL termed the tripping' lever, one end of4 which has secured to it the'cam 96, previously referred to, which operates the roller on the arm 93,'todraw other part 152 ismovable or angularly ad?-L justable about the said shaft, and is mounted: on a 4lateral extension or boss153-of the fixedl part 151of the cam.- Y Y The peripheries ofgtheisaid fixed and mgoveA` l able paits151-and 152 arel of equal radius, and in-eflect the said parts form a single,V

cani- 132, the arc of contact of which with the roller or runner131 may be increased or di` minished by angular adjustment of the mov-y able part 152.

The point-of impact of the roller 131 with thetwo-.part cam 132 is invariable, as the said roller approaches and contacts with the xed part 151 thereof. However, the pointof de- "I-i parture'of the roller ,131 from the, said cam can be varied -by adjustment of the movable part 152thereof`, and it maybe made earlier or later as reoluired.V

It will, accordingly, be understood that by means ofthe two part cam 132 the movable jaw 123 ofthe grippers of the cylinder 88 is opened in a constant position of the said cylinder,but the closing of the said jaw may be delayed by angularL adjustment ofthe mov- "f able part 152 of the said cam.

The movab-le part 152 is provided Awithan arm 154, to a pin 155 in the outer lend of which is attached a link 156. The opposite end of the link 156 is extended through a swivelling i lug 157 mounted at the endof the tripping, lever 150, and the link 156 isadjustably se-Y cured by nuts 158 to the said lug.

Attached to a pin 1:59 ina lug V160 on the trippinglever 150is a rod 161, the opposite end of which passes'through a swivelling lugvv 162 mounted in the frame 2.

On the rod 161 is ank adjustable collar 163,

and also on the rod'161and interposed be-` tween the collar'163 and the lug 1,62 isa spring 1641.

r.The lug 162 formsv an abutment for the .i

spring 164: and the latter applies pressure to the collar 163 to normally maintain the tripping lever 150 in the position shewn by full lines, in'Figure 7. f In this normal position,

` which may be-regulated` byadjustment of lock nuts 165 threaded upon 'the rod 161,v

the cam 96 is maintained in the path of the roller 95 to withdraw ,the needles 100, andthe movable part 152 ofthe cam 132,` is held in its normal position, wherein .it permits the aw.v 123 to close to make the primary fold, as abovel described.

Fixed to the cam shaft 147 is a tripping cam or ,eccentric 166, adapted to Contact .with

a roller or follower 167 mounted on a pin 168 Y in the tripping lever 150, and displace the same Aagainst thek resistance of the spring 16/1 into the positionshewn by broken lines in Figure7. 1

The tripping lever 150, when thus ldis'- placed by the tripping cam 166, is inovedinto a position wherein it holds the needle actuating cam 96 clear of the roller 95, so that the needles 100 are not withdrawn during the revolution of the cylinder 87. lioreover, in theVr position of the tripping lever 150, shewn by armA 154,7and the movable p`art'152 of the two part cam 132 has been thereby moved into a ybroken lines, the link 156v has displaced theL retardedv position, likewise indicated by 'broken lines. I In this 'retarded position of the movable part 152 of the said two part cam the closing of the gripping jaw 123 of the ycylinder 88 is delayed and does not occur until thelsaid jaws 122 and 123Ahavefmoved away from the tucking blade 113 of theA cylindery 87. Accordingly the primary foldof the paper strips would not be made.

Extending Athrough the frame 2 and rotatable therein is a shaft 169, one end of which carries a trigger arm-or trigger 170, whereas f the opposite end has fixed to it a trippingarin 171. The tripping arm-171 under the action.

of a spring 172, preferably arranged asl atorsion spring uponthe said shaft is adapted'tobecome positioned under van abutment' block or tripping piece 173 formedon the tripping lever 150 or fixed thereto, when the lever 150 is elevated by contact of thetrippingcam 1.66vwith the roller 167. f

Thetripping arm 171, when its end is posi-l tionedunder the tripping piece 173 maintainsv the tripping lever 150, in -the idle positionV shewn by broken lines in Figure 7, wherein r as yabove described, the needle actuating cam 96 occupies an idle positiomandthe movable part 152 of rthe said twopart cam is moved into a retarded position wherein it delays the closing of the grippers on the cylinder 88.

This condition will be maintained until such time as the tripping arm 171 is removed from the tripping piece 173 and so long as ythe tripping lever 150 is held inthe idle position, the needles will continue in theirv opera' tive positions projecting Vfrom the cylinder 87, and will pierce and take up pairs lofsheets from the paper stripsat each revolution, the said sheets becomingy collected and piled around the periphery of the collectingY cyvlinj der 87, as shewn in Figure l13.

As each pair of `sheets is collected onfthecylinder 87they are cutaway from the entering paper strips by thefcoaction'ofv the bladeV 136 and the rubberpad 107, and the rear or trailing `ends ofthe, sheets'are im; pelled into the longitudinal opening108',
